Heat is heat is heat. If heat is generated, heat is generated. Don't confuse
that with _temperature_ . The temperature that objects rise to will depend on a
number of properties, starting with _heat_capacity_ and eventually influenced
by _thermal_conductivity_ , convection currents in the neighborhood, etc.. A 1
Ohm aluminum and 1 ohm tungsten wire will warm up differently, even if the same
heat were generated.
